One-Star Align requires you to input all the same information as you would for the Two-Star Align procedure. However,
instead of slewing to two alignment stars for centering and alignment, the NexStar uses only one star to model the sky
based on the information given. This will allow you to roughly slew to the coordinates of bright objects like the moon and
planets and gives the NexStar the information needed to track objects in altazimuth in any part of the sky. One-Star Align
is not meant to be used to accurately locate small or faint deep-sky objects or to track objects accurately for photography.
To use One-Star Align:
Select One-Star Align from the alignment options.

Solar System Align is designed to provide excellent tracking and GoTo performance by using solar system objects
(Sun, Moon and planets) to align the telescope with the sky. Solar System Align is a great way to align your telescope for
daytime viewing as well as a quick way to align the telescope for night time observing.
Never look directly at the sun with the naked eye or with a telescope (unless you have the proper solar filter).
Permanent and irreversible eye damage may result.
Select Solar System Align from the alignment options.
